A TikTok attorney has left viewers stunned after sharing his expert advice on how to stop HR departments destroying harassment cases before they even begin.

Ryan Stygar, from San Diego, US, is a labour lawyer who has 1.5 million followers on the social media platform where he regularly shares his knowledge and experience to help others.

In a recent clip, dubbed "classic HR trap", which has racked up over one million views and over 96,000 likes, Ryan gives tips on navigating making harassment complaints.

He claims that some HR reps will want to kill the paper trail before it starts by insisting on a phone call or face-to-face conversation to discuss the alleged harassment.

However, Ryan says that by doing so, the employee could weaken their case.

He then goes on to explain how you should approach the situation instead.

"Go ahead and take the call. There's no need to get confrontational but after the call or the meeting you need to send an email re-capping what you discussed," he says in the clip.

He then includes an email template in the TikTok, which could be used as evidence in a potential court case, which details times, dates and what the complaint entails, as well as quotes from the call or meeting.

Ryan ends the video by saying: "Any employment case is only as strong as the evidence."

This advice has resonated with his viewers with hundreds of people taking to the comments section to share their thoughts.

One viewer said: "ALWAYS LEAVE A PAPER TRAIL!" followed by clapping emojis. [sic]

"Yes, and they need to stop writing 'per our discussion', write it all out!," added someone else. [sic]

"My boss is the best, she is the one who tells us to send an email after any kinda call or issue," said another person.

Some social media users also tried to work out if they are allowed to record the call with HR.

"Why not just record the call?," one person asked, to which Ryan replied: "Illegal without consent in some states, also most audio recordings clients try to give me are useless." [sic]

Another said: "Also remember, some states are at 'one-party consent' which means you can secretly record and it'll be legal." [sic]

It's worth noting different countries will also have different laws.
