Lawler has been at the chemical company on and off since 1984, when she joined PBI from university. Bayer bought PBI in 2000.
She said: I had a great time working with Bayer. It was a fantastic business to work for. This was an opportunity that came along that was too good to turn down.
The new job at Gardman will be a challenge. It’s a bigger company with more staff and a bigger turnover and it will be a new product area.
I couldn’t afford to turn it down. I’m very excited. I’ll be working alongside [Bayer founder] Paris Natar in a strategic marketing role.
Lawler will leave Bayer at the end of October. Her successor is yet to be appointed.
