Are there any cases of people losing their jobs for sticking to their interpretation of controversial findings?

In the early 1950s, Thomas E. Lee of the National Museum of Canada found developed stone tools in glacial strata at Sheguiandah on Manitoulin Island in northern Lake Huron. Geologist John Sanford of Wayne State University argued that the oldest tools from Sheguiandah were at least 65,000 years old and could be as old as 125,000. Supporters of the standard view of North American prehistory were unable to accept this dating. Thomas Lee complained: "The discoverer of the site [Lee] was persecuted, as a result of which he lost his government job and remained unemployed for a long time. He was prevented from publishing his materials, and his finds were misrepresented by several well-known authors [...] many artifacts disappeared into the National Museum's storage rooms. Because of the discoverer's refusal to fire him, the museum director, who had proposed publishing a monograph on Sheguiandah, was himself fired and forced into exile."

You promote the hypothesis that both hominids and modern humans coexisted side by side in the past.

Sanskrit scriptures from ancient India mention so-called ape-men coexisting with humans anatomically indistinguishable from us. There is abundant evidence for this—hundreds of finds. Let's take a look at one of them. According to modern archaeologists, the first hominid is Australopithecus. Last year, Ron Clark discovered a nearly complete Australopithecus skeleton in Sterkfontein, South Africa. This hominid from Sterkfontein, dated to 3.7 million years ago, has been hailed worldwide as the "oldest human ancestor." However, there is ample evidence showing that anatomically fully developed humans existed at the same time. This evidence includes footprints, artifacts, and human skeletal remains. In 1979, Mary Leakey discovered dozens of footprints in Laetoli, Tanzania. They are found in layers of hardened volcanic ash dating back 3.7 million years. Thus, the Laetoli footprints are the same age as the Australopithecus from Sterkfontein.
