I worked here 2 years and there are many females in the sales force but very few females in leadership roles. The bonus structure is completely subjective, they decide whether you contributed to your results or not, and it is not even close to the 100% of your salary that they communicated through the recruiting process. They will promote individuals to replace directors but not give title changes. I have personally witnessed that females are underpaid v. their male counterparts.
Job Satisfaction Level
I would recommend any department other than sales, as I believe those groups have demonstrated that they support women.
There are many women that work in management and supporting roles. Typically your age is more of a soft spot versus your gender. They only have unpaid maternity leave, government mandated, but it's generally a nice place to work. The company is definitely male-dominated, especially in technical roles, but the culture is SLOWLY changing.
I've worked here for 24 plus years there are women working here but some jobs are not offered. I believe they are somewhat treated fairly but Men advance much faster then women. I took maturity leave once out of four children and worked my regular job two weeks before due date. Working shift work is challenging and you need a strong marriage and support from family.
