I worked at Rona for multiple years. The environment was okay, especially at first, but it definitely was not worth it, considering the hassle you got all the time, and the lack of recognition you get. The work was relatively hard if you actually did your job (which most people didn't), and you got no recognition for caring about the job itself.
Management uses and abuses you when you are a good worker, and they tend to take advantage of the fact that it's an entry level job (the pay is garbage). There are literally 0 benefits for part-time workers except for an employee discount (which is practically non-existent now that they're changing under Lowes ownership).
I learned that management usually sucks (good managers go to better jobs) and that Rona, overall, does not care about its employees. This is also the kind of job where long-term employees are liars, two-faced, and think they rule the world and can do whatever they want.
The most enjoyable part of the job was when it was downtime and you got to work with your friends. Everything else about the job made it a place that I would not recommend to anybody sane, to work at.
Management is really bad, terrible pay, no benefits (other than the employee discount), fast-paced/stressful environment, no appreciation or acknowledgement from other workers/managers, most employees leave within a year, no job security, no opportunity to move up in company unless you've been working there for 15 years
