Some people have wonderful relationships with their bosses, others aren't such big fans and find themselves dreading going into the office.

But as we need our jobs to pay for just about everything, a number of employees often have to just suck it up and get on with their work.

One woman, who has spent the last 35 years working as a cleaner for different banks, didn't get on all too well with a manager at a branch of HSBC.

The cleaner, who would prefer to remain anonymous, just retired from her role and on her very last day decided to finally stand up to the "awful" manager and leave behind a note, encouraging her to treat people with more respect from now on.

A photo of the note has since been shared on social media, where it has gone viral.

It reads: "Hi ladies, tomorrow will be my last clean for HSBC.

"I have made up a bucket of cleaning materials for the next cleaner whoever that may be!!

"I've left the job [manager's name] after the way you dressed me down in the office, it was nothing more than aggressive and cruel but that's a reflection on your character, not mine."

It continues: "So going forward, please all of you remember:

"In a world when you can be anything, BE KIND.

"Because you are all no better than the cleaner."

The caption posted alongside the note read: "And this is why I love my mum. She's been cleaning banks for 35 years and today walked out with this lovely note left behind for that awful manager.

"Happy retirement mum - always have the last laugh eh!"

More than 135,000 people liked the post, with many also taking the time to share their thoughts.

One person replied: "Well done her! My dad was a caretaker of a school for 30 years, so many rude staff. When I started teaching I swore I would always be friendly to all staff contributing to the school."

Another wrote: "When interviewing people for jobs, I always asked the reception staff how they were treated by the candidate. A few failed the 'attitude test'."

A third added: "Never understood why people think what they do for a living reflects their importance. I was raised to believe that a job is a job and anyone getting up and going to work deserves the same respect, whether they pick up trash or run the company. Good for your mom! Respect!"
