Ham does not find the Regus survey results surprising.
"It really feels like I'm slaving away because the salary is low but the expectations are higher than Mount Everest. On average, I clock an additional 40 hours monthly.
"Work keeps piling up because the boss is too cheap to hire an additional staff and I end up shouldering the load of two," she says.
Ham, from Johor, admits she just can't take her mind off work and resents her inability to let go after work hours.
"My boss expects me to be superwoman and I don't want to let him or myself down.
Sometimes I am angry at myself because I let work encroach into my personal time," she says, adding that she plans to look for another job.
Kuala Lumpur-based finance analyst Soo, 30, left her previous job at a multinational company because she was expected to work late everyday.
"I was miserable there's only so much I could take. By the time I got home, I was so drained and had no energy left," she recalls.
Soo denies she had to stay back because of inefficiency, saying there were countless ad hoc requests and meetings that delayed her work.
"Reading and responding to e-mail from my subordinates, superiors and counterparts from overseas is already a task in itself. You'd be surprised how long that can take.
Because I liaise with colleagues from different time zones and sometimes work past midnight, my sleep patterns became abnormal. My brain just wouldn't shut down."
These days, she prioritises.
One of the top performers in her current company, Soo now leaves the office at 5.30pm or 6pm and refrains from working weekends to recharge.
"When you're too tired, you make mistakes errors you would not normally make. And when your superior points it out, it can be very demoralising because despite the many hours sacrificed, you find that all the good work is overshadowed by that one careless mistake," she says.
"That's why now I make sure that I am not overworked."
