Sales queen sacked for daring to have children in line for £200,000 compensation

Known as the 'queen of double glazing', Alison Prowse Piper, 37, suffered 'humiliating and hostile' treatment from directors at Anglian Home Improvements.

She led a division with a £90million turnover and her motivational speeches within the company were known as the 'queen's speech'.

'Humiliated': Alison Prowse Piper is set to get £200,000 after claiming she was sacked for having two children in 14 months

Directors, who had promoted her to the job of national manager of telecanvassing, had told her she was a natural leader who would soon have a seat on the board.

But after taking maternity leave twice in 14 months she said she felt 'ostracised' and her pay was cut by more than half to £30,000.

She was made redundant the day before she took summer holidays last year.

When her third child was born in 2006 - 14 months after her second - she returned from a further six months maternity leave to work for sales director Martin Troughton who said her job title was 'highfalutin' and her work was 'pathetic and crap'.

While she was giving a presentation he ridiculed her work and said her mobile phone was 'a useless brick'.

Announcing her second pregnancy in 2005, one director said: 'Oh my God, you're not, are you? I suppose I should offer you my congratulations.'

When she protested about being excluded from meetings she was told by a director 'she was being boring'. In March 2005 she complained of sexual discrimination.

Mrs Prowse Piper, of Plymouth, joined the company - one of Britain's biggest fitters of windows, garage doors and conservatories - in 1988.

After having her first child Oliver, with husband Dean Piper in 1999, she returned to work after a few weeks.

Within five years she was promoted to become the national manager of telecanvassing commanding a £72,500 annual salary for a three-day week.

Mrs Prowse Piper has won her claim that she suffered sex discrimination, sexual harassment and unfair dismissal after an employment tribunal in Exeter in July.

She told the hearing that when she returned to work after the birth of her third child she received a letter about her salary.

'I felt I was still the same person doing the same job and the same hours but I was being offered £30,000.'

She added: 'I was the person who had headed up telecanvassing and been very successful and I could not understand why I was being ostracised and amputated.'

Employment judge Mrs Christa Christensen upheld all her claims in a judgment against Anglian which was has just been released.

In her ruling, Mrs Christensen said the way Mrs Prowse Piper was treated by three different directors was ' disrespectful, dismissive and demeaning'.

The firm denied the allegations and directors said they did their utmost to help Mrs Prowse Piper return to work.

The tribunal is expected to award compensation - likely to be two or three times her salary - in November.
